Definitely AFTER!
In fact, you should remove wax before applying paint and wait at least one month after spraying or touching up to put wax back on.
Wax, silicone and oils may cause your paint to fisheye, but don’t worry, ERA Paints wax and grease remover is designed to chemically remove these contaminants.
We suggest the wax and grease remover is applied according to our instructions supplied in each shipment.
